Hi @fhahn. This patch looks be the cause of the failure reported by https://lab.llvm.org/buildbot/#/builders/176/builds/1723.  As well as on AArch64 I also see the failure on X86_64 when doing the following cross compile:

  ./bin/clang++ -target aarch64-linux-gnu --sysroot=/opt/aarch64-sysroot --gcc-toolchain=/opt/aarch64-cross-compiler -DGTEST_HAS_RTTI=0 -D_DEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -Ilib/Transforms/Scalar -I/home/pmw/projects/upstream-llvm/llvm-project/llvm/lib/Transforms/Scalar -Iinclude -I/home/pmw/projects/upstream-llvm/llvm-project/llvm/include -mcpu=a64fx -msve-vector-bits=512 -mllvm -treat-scalable-fixed-error-as-warning=false -fPIC -fno-semantic-interposition -fvisibility-inlines-hidden -Werror=date-time -Werror=unguarded-availability-new -Wall -Wextra -Wno-unused-parameter -Wwrite-strings -Wcast-qual -Wmissing-field-initializers -pedantic -Wno-long-long -Wc++98-compat-extra-semi -Wimplicit-fallthrough -Wcovered-switch-default -Wno-noexcept-type -Wnon-virtual-dtor -Wdelete-non-virtual-dtor -Wsuggest-override -Wno-comment -Wstring-conversion -Wmisleading-indentation -fdiagnostics-color -ffunction-sections -fdata-sections -O3 -DNDEBUG    -fno-exceptions -fno-rtti -UNDEBUG -std=c++14 -MD -MT lib/Transforms/Scalar/CMakeFiles/LLVMScalarOpts.dir/SimpleLoopUnswitch.cpp.o -MF lib/Transforms/Scalar/CMakeFiles/LLVMScalarOpts.dir/SimpleLoopUnswitch.cpp.o.d -o SimpleLoopUnswitch.cpp.o -c /home/pmw/projects/upstream-llvm/llvm-project/llvm/lib/Transforms/Scalar/SimpleLoopUnswitch.cpp

The failure disappears after locally reverting this patch.
